Solution Overview
Problem
Existing slatted frames for beds lack enhanced comfort and functionality, particularly in supporting both lying and sitting positions while providing adequate massage features for muscle and intervertebral disc relief.
Innovation Solution
The slatted frame design incorporates a head part that is both pivotable and translationally movable relative to the foot part, with a drive unit enabling alternating back-and-forth movement, allowing for adjustable positioning and massage functions, and features a gear arrangement to minimize noise and vibration transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the headboard is made pivotable to enable sitting position, then adaptability is improved, but mattress compression and damage occur during pivoting
Solution Approach 1:
The headboard is moved translationally in advance before pivoting occurs, creating clearance between the headboard and footboard. This preliminary translational movement prevents the mattress from being compressed or damaged during the subsequent pivoting operation, while still enabling the headboard to transition between lying and sitting positions.
2Ease of operation
If massage function is added through headboard movement, then user comfort is improved, but device complexity increases
Solution Approach 1:
The massage function is integrated into the existing headboard positioning mechanism. The same drive unit that moves the headboard for position adjustment (lying to sitting) also provides the massage function through alternating back-and-forth movements. This merging of functions adds comfort without requiring a separate dedicated massage mechanism.
Solution Approach 2:
The massage function is implemented through periodic alternating movement of the headboard back and forth in the longitudinal direction. This rhythmic motion is generated by the drive unit moving the headboard translationally in opposite directions, creating a massaging effect on the user's back and shoulders without complex additional mechanisms.
3Adaptability or versatility
If drive unit is added for translational movement, then functionality is improved, but noise and vibration increase
Solution Approach 1:
A gear arrangement is introduced as an intermediary between the drive unit and the headboard. This gear mechanism serves as a mediator that reduces the noise and vibration generated by the drive unit during translational movement of the headboard, while still effectively transmitting the driving force to achieve the desired movement capability.

AI summary
The invention relates to a slatted frame or similar mattress support, in particular for a bed, with a head section (2) serving to support at least the head of a person and a foot section (3) serving to support at least the legs and feet of a person, wherein the head section (2) is pivotable relative to the foot section (3) about a pivot axis (5) extending transversely to the longitudinal extent (4) of the head and foot sections (2, 3), characterized in that the head section (2) is designed to be translationally movable relative to the foot section (3) in the direction of the longitudinal extent (4) of the head and foot sections (2, 3) and that a drive unit (14, 63) is provided which is operatively connected to the head section (2) and is configured to move the head section (2) back and forth alternately relative to the foot section (3).
